how to obtain "par(ask=TRUE)" with trellis-plots
Dear alltogether, how can a delay like possible with par(ask=TRUE) be attained while using trellis-plots within a loop or something like that? the following draws each plot without waiting for a signal (mouse-klick), so par() does not work for that: library(nlme) for(i in 1:3) { fitlme <- lme(Orthodont) par(ask=TRUE) # does not work with trellis.... print(

Strange "Error: subscript out of bounds"
Dear all, I am trying to write a function for visualizing ordinal model results. The function works fine with some values, but then I get "Error: subscript out of bounds" even there the index should be pointing a legal item. Code is below as well as the example of failure: plotProb <- function(pre.mat, parts, split, titles, xlab="") { par(mfrow = split) n <- 1

State Space models in R
Hello everybody, I am writing a review paper about State Space models in R, and I would like to cover as many packages as I reasonably can. So far I am familiar with the following tools to deal with SS models: * StructTS, Kalman* (in stats) * packages dse[1-2] * package sspir * package dlm I would like to have some input from users who work with SS models: are there any other packages for SS

Linux NIS/NFS/Samba server bound to Active Directory
Hello all! We are currently testing the implementation of a multi-use server at my work. I am working with a Windows 2003 RC2 domain controller, and a CentOS 5 NIS/NFS/Samba server. I've followed various how-to's and researched several errors during the past sixteen hours working on this but all things I try seem to come back with empty results. I

Calling a LAPACK subroutine from R
Hello R-helpers! I am trying to call a LAPACK subroutine directly from my R code using .Fortran(), but R cannot find the symbol name. How can I register/load the appropriate library? > ### AR(1) Precision matrix > n <- 4L > phi <- 0.64 > AB <- matrix(0, 2, n) > AB[1, ] <- c(1, rep(1 + phi^2, n-2), 1) > AB[2, -n] <- -phi > round(AB, 3) [,1] [,2] [,3]

lpxelinux.0 - 6.02 - failed to load ldlinux.c32
Hello Geert Thanks for replying.. But i think i can?t use it, as i don?t reach the point where the debug module will be available.. it just pulls the lpxelinux.0 and tries to get the next download-- the ldlinux.c32 and it fails...and freezes. And the next step would be other modules i think.. if i?m wrong.. excuse me 8-).. yesterday i managed to get ipxelinux working from ipxe.org.. so the nic

Sweave, beamer and alert within code chunks
Hi all, Using Beamer, in order to highlight a piece of R code I do something like this - note the "\structure" and "\alert" commands: \begin{semiverbatim} > mleOut <- \structure{dlmMLE}(Nile, + parm = c(0.2, 120), # initial values for optimizer + lower = c(1e-7, 0)) \alert<2>{# V must be positive} > mleOut$convergence

What is the difference between S and R?

Since S and R are not completely the same, there are delicate differences between S and R, which an S book may be confusing if I want to learn R. One example is Statistical Models

Improving efficiency in "outer"-like calculation
Hello, I am doing mcmc=10000 simulations from a posterior distribution of the parameters of a mixture of K=6 normal densities. I have mcmc by K matrices simMeans, simVars and simWeights containing the simulation output: one row for each simulation, one column for each normal component of the mixture. One thing I would like to do is a plot of the posterior predictive density. In order to do that

Installing on Windows packages build on Unix
Hello, I wanted to share with a colleague a few R functions that I wrote. To this purpose, I created a small package on my machine (Unix) and emailed it to her. Now she is having troubles installing the package on her Windows machine. It seems that on her side, install.packages looks for a "zip" file - while I have created a "tar.gz" file. I tried to build the package with the

GLMM and data manipulation (2nd try)

tapply and empty subsets
I am using tapply to compute means by group, as in > tapply(y, z, mean) 1 2 3 21.00757 20.50031 NA where y is a vector and z a factor with levels 1:3. I would like to get a zero instead of the NA I get when a subset is empty. The problem is that FUN is not applied to empty cells of the ragged array. (Of course I am willing to define a function my.mean that returns
